1227 steel, m390 As a knife enthusiast, you must have an in-depth understanding of different knife materials. Among them, 1227 steel and m390 are relatively common high-quality steel materials. Let’s take a closer look at these two types of steel.
1227 steel
1227 steel, also known as 9Cr18MoV, is a high-quality stainless steel with excellent corrosion resistance and hardness. This steel mainly contains Cr, Mo, V and other elements, which can improve the hardness, wear resistance and toughness of the steel to a certain extent. When manufacturing knives, 1227 steel is often used as the blade material to ensure the durability of the knife.
Characteristics of 1227 steel
– High hardness: The hardness range of 1227 steel is between 58-60HRC; – Corrosion resistance: The Cr element it contains can form a dense oxide film on the surface of the steel, thereby improving the corrosion resistance of the steel; – Good cutting Properties: 1227 steel forms fine carbide particles during quenching, which enables it to form excellent cutting properties during cutting, thus improving processing efficiency.
Applications of 1227 steel
1227 steel is widely used to make high-quality knives, such as kitchen knives, hunting knives, folding knives, etc. Due to its high hardness and strong wear resistance, it is also commonly used to make mechanical parts such as bearings, clutch plates, and power tools.
M390
M390 is a high-quality powder metallurgy stainless steel with excellent wear resistance, hardness and corrosion resistance. The steel mainly contains elements such as Cr, Mo, and V, and also contains small amounts of elements such as Ni and Co, which can improve the hardness and wear resistance of the steel to a certain extent. When manufacturing high-end knives, M390 steel is often used as the blade material to ensure the quality and durability of the knives.
Features of M390
– High hardness: The hardness range of M390 is between 58-62HRC; – Corrosion resistance: The Cr element it contains can form a dense oxide film on the surface of the steel, thereby improving the corrosion resistance of the steel; – Good machinability : M390 steel forms fine carbide particles during quenching, which enables it to form excellent machinability during cutting, thereby improving processing efficiency.
Application of M390
M390 steel is widely used in making high-quality knives, such as folding knives, hunting knives, medical instruments, etc. Due to its high hardness and strong wear resistance, it is also often used to make precision mechanical parts such as high-end watches.
common problem
1. What is the difference between 1227 steel and M390 steel?
1227 steel and M390 steel are both high-quality steels, but M390 steel is more wear-resistant and harder than 1227 steel. Therefore, M390 steel is more commonly used as a blade material when manufacturing high-end knives.
2. What is the hardness range of 1227 steel and M390 steel?
The hardness range of 1227 steel is between 58-60HRC, while the hardness range of M390 steel is between 58-62HRC.
3. What is the difference between the production processes of 1227 steel and M390 steel?
1227 steel is made through traditional processes such as electric furnace heating, forging, and quenching, while M390 steel is made through powder metallurgy processes, which can improve the uniformity and stability of the steel to a certain extent.
